"Three, two, one!" Qu Shansi's voice fell, and he let go at the same time. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Everyone stared closely, but saw that the feather was as fast as an iron ball, as if it was being dragged by someone, and it fell to the ground with a 'whoosh'.

Landing at the same time!

"What?" The scene in front of him once again broke everyone's thinking, and they all froze.

"Hehe, do you want to know why? You'll learn later!" Qu Shansi still explained, and withdrew his hand.

But as he spoke, he forgot to control the absolute vacuum, and only heard a deafening sharp explosion, and the vacuum collapsed.

"Do you want to know why this is? You will learn it later!" Qu Shansi took local materials, continuously arousing the curiosity of the teenagers, "That's all for today, the academy will give you some materials later, which is the tool you need to prepare, and you can officially come to class tomorrow!"

Qu Shansi left with his hands in his hands, arrogant, and he didn't even care about a few princes.

Then someone came in again, and sure enough, they distributed a pile of materials to the students.

"Huh?" Ji Yun looked at the information in his hand, it was actually handwritten.

Ji Yun has long done research on the scientific and technological civilization of this world, and although there are many books in his home, almost all of them are handwritten, and even a few are engraved on bamboo boards.

Seeing this handwritten information at this moment, Ji Yun could immediately conclude that the Gewu Academy had not yet researched the printing technique!

There is papermaking technology, and the paper is soft and white, clean, and the technology is highly mature.

"If printing technology ...... developed"

Today's attitude towards his father and son made Ji Yun feel a sense of crisis in his heart, even the emperor didn't trust it, let alone what would happen in the future, if he wanted to save his life in the future, he was afraid that he would have to do something.

"But the ink of printing..."Ji Yun remembered this most difficult problem to solve, ink is obviously not suitable for printing, take engraving printing as an example, if you print with ink, just like the printing plate used by the folk to print the dark currency in the previous life, the printed dark currency will shrink and twist after the water is dry, it is not desirable, and the failure rate is extremely high.

"Huh?" his gaze suddenly drew to the seal at the end of the document.

"Even the ink is there, isn't the ink simpler?" Ji Yun was overjoyed.

It is impossible to simply rely on cultivation to give the father and son a way to live, at least in a short period of time, and in a short period of time, no one dares to guarantee that the emperor will attack them, although the possibility is relatively low, but it does not mean that it is impossible.

So he could only rely on other means, Ji Yun remembered printing, and he already had the best way in his heart.

He retracted his gaze and glanced at the words on the materials, which were all the things that the students needed to prepare, pen, ink, paper, inkstone, rope, and even a foot-long ruler.

"The smallest unit of distance is minutes, which is really troublesome!" Ji Yun saw the ruler, and suddenly remembered that the distance unit in this world, the highest is li, and then zhang, ruler, inch, and minute, and even the imperial court does not have a perfect distance unit system.

He was thinking, and suddenly felt that the light around him was dim, and when he looked up, he saw Ji Shaohong and Wen Cheng pacing over and surrounding him.

"Brother Yun, let's discuss something, how about it?" Ji Shaohong stretched out his hand to put his arm around Ji Yun's shoulders and walked out of the hall.

Ji Yun frowned: "What's the matter?"

Ji Shaohong stared at him, and slowly squeezed out a few words from between his teeth: "You, immediately, drop out of school!"

"Why?" Ji Yun smiled instead of being angry.

"Why?" Ji Shaohong regretted, "You only have the qualifications of a fool, the Kit Kat and Lewd Skills of the Gewu Academy need to be cultivated to be blessed, can you?" My good brother, for my sake, you just drop out of school!"

Ji Yun stretched out his hand and pushed away Ji Shaohong's hand, and smiled slightly: "The emperor allowed me to stay, but you want me to leave?"

Ji Shaohong's face sank: "You can not come by yourself!

Ji Yunwaner: "The emperor asked me to stay, if I don't come, wouldn't it be a protest?" I'm sorry, I still want to stay with this head!"

In fact, Ji Yun had the idea of not coming for a long time, but he had come to the Gewu Academy once, and knew that the Gewu Academy would have good pills from time to time, and if he was in the Gewu Academy, he would be able to grasp the news as soon as possible.

"Don't toast and don't eat and drink! If you quit school on your own, your father won't say anything, and your father will at least give your father face!" Ji Shaohong's face was cold, "If you come tomorrow, I will make you regret it!"

After speaking, several people sneered and walked away.

Yun Gui walked over and sighed: "Actually, I also agree with you dropping out." ”

Ji Yun raised his head and looked at Yungui in surprise.

"I can guarantee that if you come to school tomorrow, these people will probably beat you up!" Yun Gui shook his head, "I can guess their purpose, they are to beat you, you don't dare to come to school again!"

"I know!" Ji Yun nodded.

"Then will you come back tomorrow?" Yungui's anger began to brew again.

"Of course!" Ji Yun seemed to hear the Arabian Nights, "Why don't I come?"

Yungui was furious: "You will be beaten when you come?" Where do you let the prince's face go?"

Ji Yun still looks like a dead pig who is not afraid of boiling water: "So what?"

"You!" Yun Gui was angry and took a deep breath, "Brother, they will really kill you!" Today, if the emperor gives the prince such a faceless face in front of the ministers, they will be even more unscrupulous, don't you understand?"

Ji Yun laughed: "Let's go, go back!"

Yun Guiqi almost turned his back on his anger, and by the time he came to his senses, Ji Yun had already left.

"Bastard!Ji Yun, you're a bastard!" Yun Gui roared at the empty doorway.

"Brother, thank you!But if I want my father and son to live, I have to break through from this Gewu Zhizhi Academy!At the very least, I have to mix up a knighthood first!" Ji Yun listened to Yun Gui's roar and muttered in his heart.

There was nothing to do all the way, and when he returned home, Ji Chongxiao also happened to come back from the palace, and the father and son entered the door with their front and back feet, but their faces were gloomy as water.

However, when Ji Chongxiao saw Ji Yun, he smiled: "How is it, what are you gaining today?"

Ji Yun also smiled and recounted the fact that the two iron balls landed at the same time.

The two of them were talking, but their feet were both walking in the same direction, their mother's bedroom.

"Father, does your cultivation have any of the seven changes in the Yellow Realm?" From a distance, he saw Gong Yiwen sitting in the sun, and a few maids next to him were playing with her, Ji Yun suddenly asked, if he saw Ji Chongxiao's behavior outside Qituo Mountain yesterday, he would not have asked this question.

Ji Chongxiao was stunned, and for a while he didn't know why his son asked why, so he smiled casually: "Almost! Did you see those people in the Gewu Academy doing their cultivation?"

Ji Yun nodded: "The Dao Realm is so powerful..."

This is Ji Yun's true words, even if it is such high-tech in the previous life, it can't create an 'absolute vacuum', it is an ideal thing that does not exist, but Qu Shansi waved his hand to create an absolute vacuum field, although Ji Yun is not sure whether it is really an absolute vacuum, but even if he makes a vacuum, it is very powerful.

With the cognitive comparison between the two worlds, this was the first time he realized the power of the so-called Dao Realm.

"Cultivating civilization can do what scientific and technological civilization can't do in some fields!"

"Haha, that Qu Shansi is just a mere Yellow Realm Seven Changes, only when the Yellow Realm Nine Changes, can you be regarded as getting rid of the mortal body..."Ji Chongxiao stopped at the right time, and between his words, it seemed that Qu Shansi could be judged from the 'Seven Changes' in Ji Yun's mouth, and patted Ji Yun on the shoulder, "You will also reach his height in the future!"

The father and son played with Gong Yiwen for a while, and Gong Yiwen shouted to sleep, and after coaxing her to sleep, the father and son came to the door and sat in the sunset, each with their own thoughts, without saying a word.

"Father, is the emperor going to attack you?" Ji Yun, who returned home, no longer covered it.

Ji Chongxiao was silent, and after a long while, he sighed: "Emperors have been like this since ancient times, which of the battlefield generals with high achievements can enjoy their old age in peace? The emperor is giving me a choice!"

Ji Yun thought for a while, frowned, and said, "Retreat bravely?"

Ji Chongxiao nodded: "In the past fifteen years, the national fortune has gradually prospered, the people's livelihood is rich, and the surrounding area is relatively stable. ”

"What if not?" Ji Yun's voice was cold.

Ji Chongxiao suddenly looked up at his son.

Ji Yun ignored it, and his voice was still cold: "Why do you want others to sit on the rivers and mountains you have beaten down?"

Ji Chongxiao looked at his son in a daze, and after a long time, he slowly stood up, walked to his house, and walked a few steps, his lonely voice came: "The meaning of my life, in addition to raising you as an adult, is to find the murderer of your mother." ”

Ji Yun looked at the back of his father leaving, and muttered in his heart: "If there is no power, how can you find the murderer?"

Back in the room, Ji Yun sat cross-legged on the bed, shook his head, shook off his troubled thoughts, cultivated for a while, and suddenly remembered the Jing Yuan Pill.

He hurriedly got out of bed and rummaged out of the cabinet, this is just a Jingyuan Pill, but why is it in the Tianzi Workshop of Gewu Academy?

Thinking of this, his heart moved, his mind urged the keyboard, held the elixir in his hand, and pressed F1 with his mind.

"Jing Yuan Dan is fused with dragon scales and refined, after taking it, it can greatly improve the cultivation, only one to three changes in the Yellow Realm can be taken in, if ordinary people take it, the Yellow Realm can be directly promoted to the second change of 'Nine Cows and Two Tigers', if the person who cultivates the dragon recipe takes it, one change can directly improve the cultivation to the realm of three changes of 'copper skin and iron bones'. ”

The effect of this pill appeared in his brain, Ji Yun was taken aback, this pill actually fused with dragon scales?

In the entire world, there are only so many people who cultivate the dragon transformation technique, who would be willing to peel off a piece of dragon transformation scales to refine such an elixir?

However, to improve the cultivation of the first-grade Dao realm, this elixir is indeed against the sky.

Ji Yun knows that the lowest realm of the Dao Realm is the Yellow Realm, and there are already songs recited on the ninth layer of the Yellow Realm: one change is 'Convincing Qi Bigu' pure body, the second is 'Nine Oxen and Two Tigers' is infinitely powerful, the third change is 'copper skin and iron bones' are indestructible, the fourth change is 'Swallowing Gold Fossils' to strengthen the internal organs, the fifth change is 'Hundred Tricks Gathering Spirits' Qi is free, the sixth change is 'practicing Qi Chenggang' and the whole body is treasured, the seventh change is 'taking off from the ground' and starting to fly, the eighth change is 'Three Flavors of True Fire' refining the golden body, and the ninth change is 'Glazed Jade Body' without disease.
